All cities in Johto are named after plants or things related to plants (New Bark Town, Ecruteak City, Cianwood City, etc.). Professor Elm is the resident Pokémon Professor and gives Trainer's a choice between Chikorita, Cyndaquil or Totodile as their starter Pokémon.
Cities, routes, and other locations
Johto has ten towns and cities. The Safari Zone Gate and Frontier Access act as towns, but they appear to be more of a tourist destination and are not considered cities or towns. As Johto has no autonomous Pokémon League, Kanto shares a League with the region, which borders between Johto and Kanto. Because of this, the two regions share a connection with each other, and unlike any other region, they are able to be traversed to with relative ease. Due to this landmass connection, the geography of Johto is relatively similar to that of its neighbor region.
The Johto region has 20 different routes, which are passages permitting Trainers to travel from one location to the next with relative ease. Johto and Kanto share the same route system, and therefore starts at Route 29, picking up from where Kanto's left off at Route 28. The numbered routes count up to 48, with Routes 47 and 48 leading off into the far west. Compared to the Kanto region, there aren't many sea routes; there are many land routes and mountains. Some areas such as Route 33 are constantly raining, or are purged with other weather conditions.
The connecting landmass between Kanto and Johto doesn't appear to be a fine line; but more or less a blurry one. Route 28 is technically owned by Kanto; however, it bridges the border between the two regions, making it the only route in history that enters two regions at one time. This is similar to Routes 26 and 27, that are strictly Kanto locations.
